In some embodiments, controller 104 may include training set 128. In some embodiments, controller 104 may be configured to receive training set 128 and/or a parameter set of the training set 128, wherein the controller 104 may create a local object, data structure, and/or the like.

Controller 104 may be configured to receive a battery datum 144 from a battery sensor 140 on battery pack 112.

For example, sensor suite may measure a battery temperature and a battery charge level. In an embodiment, use of a plurality of independent sensors may result in redundancy configured to employ more than one sensor that measures the same phenomenon, those sensors being of the same type, a combination of, or another type of sensor not disclosed, so that in the event one sensor fails, the ability to detect phenomenon is maintained. Battery datum 144 may be correlated to a temperature of battery pack 112 in training set 128. For example, flight plan labels 132 may include battery datum 144 for training set 128 to correlate to battery temperature labels 136. Training set 128 may be configured to correlate any stage, phase, mode, and/or maneuver of a flight plan in the flight plan labels 132 to battery temperature labels 136. Training set 128 may alternatively or additionally correlate any of the potential inputs described herein and any datum included in flight plan labels 132 to other battery datum 144 concerning battery pack 112, including state of charge,

Still referring to FIG. 1 , controller 104 may be configured to receive an environmental datum from an environmental sensor 152. As used in this disclosure, “environmental datum” is an element of data representing an environmental metric. As used in this disclosure, an “environmental metric” is a phenomenon associated with an environment external to an electric vehicle such as weather conditions and includes a vehicle's location. Environmental metric may include measurements of ambient temperature, barometric pressure, air velocity, motion, various magnetic, humidity, wind velocity, oxygen, and/or location of electric vehicle 108.

An environmental sensor may include a geospatial sensor. As used in this disclosure, a geospatial sensor may include optical/radar/Lidar, Global Positioning System (GPS), and may be used to detect electric vehicle 108 location including longitude and latitude, electric vehicle speed, electric vehicle altitude and whether the electric vehicle is on the correct location of the flight plan. In an embodiment, an environmental sensor may sense one or more environmental conditions or parameters outside electric vehicle 108, inside the electric vehicle 108, or within or at any component thereof, including without limitation an energy source, a propulsor, or the like. The environmental sensor may further collect environmental information from the predetermined landing site, such as ambient temperature, barometric pressure, air velocity, motion sensors which may include gyroscopes, accelerometers, inertial measurement unit (IMU), various magnetic, humidity, and/or oxygen. The information may be collected from outside databases and/or information services, such as Aviation Weather Information Services. Battery sensor 140 may detect an environmental parameter, a temperature, a barometric pressure, a location parameter, and/or other necessary measurements. Environmental sensor 152 may include a wind sensor. In some embodiments, wind sensor may be configured to measure a wind metric and generate a wind datum based on wind metric. A “wind datum” may include data of wind forces acting on an electric vehicle. Wind datum may include wind strength, direction, shifts, duration, or the like. For example, and without limitations, battery sensor 140 may include an anemometer. An anemometer may be configured to detect a wind speed. In one or more embodiments, the anemometer may include a hot wire, laser doppler, ultrasonic, and/or pressure anemometer.

With continued reference to FIG. 1 , controller 104 may be configured to receive a location datum 148 of electric vehicle 108. As used in this disclosure, “location datum” is datum based on a current position of electric vehicle 108 (also referred to in this disclosure as a “current vehicle position”). Controller 104 may be configured to receive location datum 148 from an environmental sensor 152 configured to measure a location. Environmental sensor 152 may be configured to detect a current position of electric vehicle 108 and generate location datum 148 based on the current vehicle position. A current vehicle position may include a geographical moment of electric vehicle 108. For example, and without limitations, current position of electric vehicle 108 may include a geographical location and/or an orientation of electric vehicle 108. A current vehicle location may include any data describing a geographical moment of electric vehicle 108 at present time. Current vehicle location may be continually received by controller 104 so that the geographical moment of electric vehicle 108 is always known by controller 104. Controller 104 may be configured to update flight plan 120 based on location datum 148. Battery model 116 may then receive flight plan 120 that has been updated based on location datum 148 and generate a new temperature output 124 as a function of training set 128 and the flight plan 120. Environmental datum, including location datum 148, may be correlated to a temperature of battery pack 112 in training set 128. For example, flight plan labels 132 may include location datum 148 for training set 128 to correlate to battery temperature labels 136.

Still referring to FIG. 1 , controller 104 may receive temperature output 124 from battery model 116 and compare it to a threshold temperature. As used in this disclosure, “threshold temperature” is a specified temperature associated with a risk of harm to battery pack 112, electric vehicle 108, and/or electrical subsystems of the electric vehicle 108. Controller 104 may be configured to produce an automated response such as a warning if temperature output 124 exceeds threshold temperature. Controller 104 may be configured to provide an alert to user if temperature output 124 exceeds threshold temperature. For example, controller 104 may be communicatively connected to a display, speakers, pilot controls, and/or pilot seat to provide a visual warning, audible warning, and/or a haptic warning. Warning may be onboard electric vehicle 108 and/or at a remote site.

With continued reference to FIG. 1 , controller 104 may be configured to generate a revised flight plan 156 if temperature output 124 exceeds a threshold temperature. Revised flight plan 156 may be generated prior to execution of flight plan 120, such as pre-flight planning, and during execution of the flight plan 120, such as while electric vehicle 108 is in-flight. Controller 104 may be communicatively connected to a database including landing sites. Controller 104 may be configured to select an alternate landing site, such as landing site in a database and generate revised flight plan 156 with the selected alternate landing site. Battery model 116 may be configured to then generate temperature output 124 as a function of training set 128 and revised flight plan 156. Additional disclosure related to selecting a landing site can be found in U.S. patent application Ser. No. 17/528,673 entitled “SYSTEMS AND METHODS FOR IN-FLIGHT RE-ROUTING OF AN ELECTRIC AIRCRAFT FIELD OF THE INVENTION”, the entirety of which in incorporated herein by reference. Controller 104 may also be configured to generate revised flight plan 156 with an alternate landing site inputted by a user, and battery model 116 may be configured to generate temperature based on the revised flight plan 156. If temperature output 124 generated by battery model 116 as a function of revised flight plan 156 exceeds threshold temperature, controller 104 may be configured to then generate a different revised flight plan 156, which may differ from the prior revised flight plan 156 by landing site, mode of landing such as fixed-wing landing or rotor-based landing, speed, trajectory, altitude, and/or the like.

Still referring to FIG. 1 , battery model 116 may be configured to continuously or periodically output current temperature output 124 based on current battery datum 144 received from battery sensor 140 and/or updated flight plan 120 based on current vehicle location. For example, battery model 116 may be configured to update temperature output 124 while electric vehicle 108 is in use, such as an electric aircraft in flight, as a function of current battery datum 144 received from battery sensor 140 that is based on a current temperature of battery pack 112. If battery model 116 generates temperature output 124 that exceeds threshold temperature, controller 104 may be configured to generate revised flight plan 156 and/or generate an alarm as discussed above. Battery pack 112 may be monitored by a pack monitoring unit (PMU) consistent with disclosure of PMU in U.S. patent application Ser. No. 17/529,583 entitled “A PACK MONITORING UNIT FOR AN ELECTRIC AIRCRAFT BATTERY PACK AND METHODS OF USE FOR BATTERY MANAGEMENT”, the entirety of which in incorporated herein by reference.

A “machine learning process,” as used in this disclosure, is a process that automatedly uses training data 604 to generate an algorithm that will be performed by a computing device/module to produce outputs 608 given data provided as inputs 612; this is in contrast to a non-machine learning software program where the commands to be executed are determined in advance by a user and written in a programming language.

Still referring to FIG. 6 , “training data,” as used herein, is data containing correlations that a machine-learning process may use to model relationships between two or more categories of data elements. For instance, and without limitation, training data 604 may include a plurality of data entries, each entry representing a set of data elements that were recorded, received, and/or generated together; data elements may be correlated by shared existence in a given data entry, by proximity in a given data entry, or the like.

Multiple categories of data elements may be related in training data 604 according to various correlations; correlations may indicate causative and/or predictive links between categories of data elements, which may be modeled as relationships such as mathematical relationships by machine-learning processes as described in further detail below. Training data 604 may be formatted and/or organized by categories of data elements, for instance by associating data elements with one or more descriptors corresponding to categories of data elements. As a non-limiting example, training data 604 may include data entered in standardized forms by persons or processes, such that entry of a given data element in a given field in a form may be mapped to one or more descriptors of categories. Elements in training data 604 may be linked to descriptors of categories by tags, tokens, or other data elements; for instance, and without limitation, training data 604 may be provided in fixed-length formats, formats linking positions of data to categories such as comma-separated value (CSV) formats and/or self-describing formats such as extensible markup language (XML), JavaScript Object Notation (JSON), or the like, enabling processes or devices to detect categories of data.

Machine-learning algorithms and/or other processes may sort training data 604 according to one or more categorizations using, for instance, natural language processing algorithms, tokenization, detection of correlated values in raw data and the like; categories may be generated using correlation and/or other processing algorithms. As a non-limiting example, in a corpus of text, phrases making up a number “n” of compound words, such as nouns modified by other nouns, may be identified according to a statistically significant prevalence of n-grams containing such words in a particular order; such an n-gram may be categorized as an element of language such as a “word” to be tracked similarly to single words, generating a new category as a result of statistical analysis. Similarly, in a data entry including some textual data, a person's name may be identified by reference to a list, dictionary, or other compendium of terms, permitting ad-hoc categorization by machine-learning algorithms, and/or automated association of data in the data entry with descriptors or into a given format. The ability to categorize data entries automatedly may enable the same training data 604 to be made applicable for two or more distinct machine-learning algorithms as described in further detail below. Training data 604 used by machine-learning module 600 may correlate any input data as described in this disclosure to any output data as described in this disclosure.

A “machine-learning model,” as used in this disclosure, is a mathematical and/or algorithmic representation of a relationship between inputs and outputs, as generated using any machine-learning process including without limitation any process as described above, and stored in memory; an input is submitted to a machine-learning model 624 once created, which generates an output based on the relationship that was derived. For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model 624 may be generated by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training data 604 set are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process is sometimes referred to as deep learning.

For instance, a supervised learning algorithm may include flight elements and/or pilot signals as described above as inputs, autonomous functions as outputs, and a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs is associated with a given output to minimize the probability that a given input is not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation is incorrect when compared to a given input-output pair provided in training data 604.
